Reply To: How to work with STL file?

[pgl]

The best way to work with STL files is to import the STL file into ANSYS Spaceclaim and then convert into a CAD geometry file such a Parasolid. The CAD geometry can then be used by ANSYS Mechanical and other ANSYS simulation products. 

Note that generally *.STL files are not able to capture geometry appropriately and ANSYS Spaceclaim helps to repair the .STL file if needed.
